Title: Using SLM MIDI to send Control changes to GCX Audio Switcher
Post by: tchopper on July 10, 2014, 06:14:05 AM
I have a GCX Looper that I want to be able to send control changes to per the users manual these are the commands to be sent from "other" midi controllers:

The GCX responds to MIDI Control Change messages sent on channel 16 only. A data value of 0 turns the loop off, a data value of 127 turns the loop on. Controller numbers are as follows:
Audio Loop or Latched Switch
Loop #1 = controller #80
Loop #2 = controller #81
Loop #3 = controller #82
Loop #4 = controller #83
Loop #5 = controller #84
Loop #6 = controller #85
Loop #7 = controller #86
Loop #8 = controller #87

Say for example I wanted to create a midi preset that activated only loop #1, how would I do that in SLM?

Here are some MIDI hex values:

BF = control change on channel 16
50 = controller number 80 (loop 1)
57 = controller number 87 (loop 8)
00 = value 0 (off)
7F = value 127 (on)

So you could enter this into the raw MIDI field to turn on loop 1:

BF 50 7F

Or enter this to turn off loop 4:

BF 53 00

You might want to create a preset the turns off all loops:

BF 50 00
BF 51 00
BF 52 00
BF 53 00
BF 54 00
BF 55 00
BF 56 00
BF 57 00
